Properties

backgroundImageAsset → String?
Optional background image asset path for realistic moon appearance
final
date → DateTime
DateTime to show. Even hour, minutes, and seconds are calculated for MoonWidget
final
earthshineColor → Color
Color of dark side of moon
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
labelPosition → MoonLabelPosition?
Where to display the phase label relative to the moon. Null = no label.
final
labelSpacing → double
Spacing between the moon widget and the label.
final
labelStyle → TextStyle?
Optional style for the phase label text.
final
moonColor → Color
Color of light side of moon
final
phaseLabels → Map<MoonPhaseName, String>?
Translated phase name strings keyed by MoonPhaseName. Falls back to built-in English labels for any missing key. Pass your own i18n strings here:
final
pixelSize → double
Pixel size for shadow rendering. Smaller values = smoother but heavier. Default is 1.0. Use 0.5 for smoother edges.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
shadowRatio → double
Shadow radius ratio for image mode (0.0 ~ 1.0). Use this to match shadow to actual moon area in image. 1.0 means shadow radius = size/2, 0.8 means shadow radius = size/2 * 0.8. Defaults to 1.0.
final
size → double
Decide the container size for the MoonWidget
